EnzoTech Introduces Revolutionary Spring Loaded Uni-Holder® Snap-On Clips for BGA Heat Sinks
EnzoTech introduces Uni-Holder® clips to be used with its high performance, cold forged BGA heat sinks. Uni-Holder® is smartly designed to utilize the space between BGA package and its solder balls. It solves all the problems relating to heat sink attachment such as space, pressure and ease of assembly by using the principle of lever to provide optimum vertical pressure in a limited space
In addition it replaces unreliable thermal tape, Uni-Holder® allows engineers to use heat sinks with phase change TIM’s which have much better thermal performance than tapes. TIM performance is pressure sensitive. Uni-Holder® is engineered to provide constant pressure to obtain best performance from phase change TIM.
Conventional Z-wire and spring loaded push pin attachment methods require mounting holes on the PCB that can make routing more difficult. These also do not allow attachment of fan on top of heat sink. There are other plastic clips available that can attach the heat sink by snapping it onto the chipset, but the clips usually require special tools to attach and remove and some do not provide sufficient pressure.

Recent test data shows 2%-4% performance improvement for the same heat sink used with Uni-Holder. Comparing the results, it shows Uni-Holder® can apply sufficient pressure on the TIM for better performance.
Major advantages of using Uni-Holder® heat sinks are:
- Reliable attachment Pass Shock (50G) and Vibration Tests (test data available upon request)
- No mounting holes on PWB are required
- Easy installation and removal. No tools required.
- Stable and reliable pressure provide optimum heat sink performance
- May use Phase Change TIM to reduce interface resistance
- Footprints available: 19x19mm to 40x40mm
- Can be used for fan sink attachment
